KSP2 brought more life to the sizes present in KSP1, giving them labels and colors according to each diameter. Here is some information about them. This list does not contain all possible sizes as defined by the game, and it also contains modded part sizes. For a list of all the stock game part sizes available to be used in the Core Part Data module and part JSON definitions files, see Size Category.
